Substitute Part Grouping Explanation

Substitution eligibility for the ISL6161CB is determined by strict equivalence across the following critical parameters:

• Base Product Number: ISL6161 (same functional family)
• Type: Hot Swap Controller with 2-channel configuration
• Package / Case: 14-SOIC form factor (mechanical and electrical compatibility)
• Voltage - Supply: 10.5V ~ 13.2V (power rail compatibility)
• Current - Supply: 8 mA (system power budget alignment)
• Operating Temperature: 0°C ~ 70°C (thermal operating range)
• Applications: PCI Express® (functional application domain)
• Features: Latched Fault, Programmable Current Limit, Programmable Fault Timeout (functional feature set)
• Internal Switch(s): No (circuit topology consistency)

The ISL6161CBZA meets all substitution criteria and is classified as an active product, providing continued availability and support.

Parameter Comparison

Engineering Selection Recommendations

The ISL6161CBZA is the direct functional equivalent to the ISL6161CB. Both components share identical electrical specifications, channel configuration, package form factor, and feature set. The primary distinction is product lifecycle status: the ISL6161CB is obsolete, while the ISL6161CBZA maintains active product status with ongoing manufacturer support and availability.

For new designs or system maintenance requiring hot swap control in PCI Express applications, the ISL6161CBZA provides equivalent performance with the advantage of active product support. Both components are RoHS non-compliant and REACH unaffected, maintaining consistent compliance posture.

Frequently Asked Questions (FAQ)

Q: Can ISL6161CBZA be used as a direct replacement for ISL6161CB?

A: Yes. The ISL6161CBZA is electrically and mechanically equivalent. Both components feature identical 2-channel hot swap control, 14-SOIC packaging, 10.5V–13.2V supply voltage range, and programmable current limit and fault timeout functions. Pin-for-pin compatibility and functional equivalence are confirmed across all specified parameters.

Q: What is the difference between ISL6161CB and ISL6161CBZA?

A: The components are functionally identical. The difference is product status: ISL6161CB is obsolete, while ISL6161CBZA is active. The ISL6161CBZA offers continued availability and manufacturer support.

Q: Are there any package or mounting differences?

A: No. Both components use the 14-SOIC (0.154", 3.90mm Width) surface mount package. PCB layout and footprint compatibility are identical.

Q: What supply voltage range is required?

A: Both components operate within 10.5V to 13.2V. System power rails must remain within this range for proper operation.

Q: Can these components be used in non-PCI Express applications?

A: These components are specified for PCI Express applications. Use outside this application domain requires verification against detailed functional specifications not provided in this reference.

Q: What is the operating temperature range?

A: Both components operate from 0°C to 70°C. System thermal design must maintain component junction temperature within this range.
